Well, sort of. The technical meaning of meta is that is "one level up" in abstraction. So you have a game, and it has rules. Do the rules have rules? Yes, a rule about a rule (for instance, saying that 'all game rules should be fair') is a meta-rule. It's a rule about rules. Or take mathematics...you can do math with actual numbers, but you can also do math about math. for instance, there are branches of number theory that are essentially math about math...that's meta-math. Data about data is meta-data. Anything that references itself but from a higher, wider perspective is meta.
I wouldn't say that a community forming around a game is meta, unless the community was a game too. Same with EC tunnel, I wouldn't call that meta...it's a game WITHIN a game but that doesn't make it meta. It if were a game ABOUT a game then yeah.
